サンギヘコノハズク Otus collari

A small, cryptically patterned brown owl confined to the island of Sangihe. Largely brown with scattered black streaks and patches and some indistinct pale markings on the wings. Occurs in forest, plantations, and patches of trees from the lowlands into the foothills. Unmistakable: the only small owl on the island, and the only one there with ear tufts. Gives a strident, high-pitched single “peuw” song note.
